Abstract
A upper clamping and conveying device for adjusting pitching force, pinches the adjustment of power for fast open form roll leveller.Pinch roll bearing block one end is connected with turning beam, with bearing pin between turning beam and frame, pad connects, the bearing block other end and connecting rod pass through pin shaft joint, connecting rod is equipped with pad and the disc spring pinching power size can be regulated, flange and sleeve pipe utilize attaching nut, double threaded screw is fixed in frame, adjusting screw(rod) is spun in flange, on adjusting screw(rod), flange top is rotary with locking nut, on adjusting screw(rod) top, taper faced washer is equipped with at connecting rod top, spheric washer adjusting nut is pressed on taper faced washer, flange is equipped with scale, connecting rod inside is opened oil duct and is installed through type lubricating cup at head.The present invention by pinch bearing block linear slide and change swing into, cancel cylinder or hydraulic jack, produce regulating stretch by disc spring, utilize lever principle that the elastic force of disc spring is zoomed into the power of pinching, can the sheet material of self adaptation different-thickness, without the need to artificial adjustment.
Description
Technical field
The present invention relates to metallurgical technology field, particularly a kind of upper clamping and conveying device of the adjusting pitching force for fast open form roll leveller.
Background technology
In modern metallurgy industry, clamping and conveying device is widely used, with distinct device with the use of, threading can be played, turn to, form the effect such as tension force, carrying roller.On roll leveller, clamping and conveying device can improve bite condition.
Clamping and conveying device common structure pinches fixing under being, above pinch and utilize cylinder or hydraulic jack and bottom pinch roll to produce clamping force.And mainly there is following defect in existing upper clamping and conveying device:
1, adopt air pressure or hydraulic control, clamping and conveying device needs constant voltage at work, higher to the seal request of whole pipeline, and constant pressure, the power of pinching cannot regulate; Pinch the sheet material of different-thickness, need manual operation to adjust, affect production efficiency.
2, bearing block moves along cylinder or hydraulic jack axis, installs slide plate between bearing block and frame, and needs to locate pinch roll axis direction.Because bearing block installation accuracy requires high, the mounting and adjusting difficulty of slide plate, charging-up lubricant oil fat is comparatively frequent, reduces precision after wearing and tearing, needs periodic replacement, adds and safeguard use cost.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is the upper clamping and conveying device providing a kind of adjusting pitching force, to realize the convenient object regulating the power that pinches.
For achieving the above object, pinch roll bearing block one end of the present invention is connected with turning beam, with bearing pin between turning beam and frame, pad connects, it is characterized in that: the bearing block other end and connecting rod pass through pin shaft joint, connecting rod is equipped with pad and the disc spring pinching power size can be regulated, flange and sleeve pipe utilize attaching nut, double threaded screw is fixed in frame, adjusting screw(rod) is spun in flange, on adjusting screw(rod), the top of flange is rotary with locking nut, on the top of adjusting screw(rod), taper faced washer is equipped with at the top of connecting rod, spheric washer adjusting nut is pressed on taper faced washer, flange is equipped with scale, connecting rod inside is opened oil duct and is installed through type lubricating cup at head.
The present invention by pinch bearing block linear slide change swing into, cancel cylinder or hydraulic jack, produce adjustable elastic force by disc spring, utilize lever principle that the elastic force of disc spring is amplified and formed with bottom pinch roll and pinch power, can the sheet material of self adaptation different-thickness, without the need to artificial adjustment.
Accompanying drawing explanation
Fig. 1 is structural representation sketch of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, bearing block 16 one end of pinch roll 17 of the present invention is connected with turning beam 18, with bearing pin 19 between turning beam 18 and frame, pad 1 connects, bearing block 16 other end is connected by bearing pin 15 with connecting rod 14, connecting rod 14 is equipped with pad 2 12 and the disc spring 13 pinching power size can be regulated, flange 11 and sleeve pipe 6 utilize attaching nut 4, double threaded screw 5 is fixed in frame, adjusting screw(rod) 3 is spun in flange 11, on adjusting screw(rod) 3, the top of flange 11 is rotary with locking nut 10, on the top of adjusting screw(rod) 3, taper faced washer 8 is equipped with at the top of connecting rod 14, spheric washer 7 adjusting nut 2 is pressed on taper faced washer 8, scale 9 flange 11 is equipped with, connecting rod 14 inside is opened oil duct and is installed through type lubricating cup 1 at head.
Rotate adjusting screw(rod) 3, disc spring 13 is compressed by pad 2 12, elastic force tightens locking nut 10 after reaching requirement, in order to ensure that elastic force is balanced, connecting rod 14 has installed spheric washer 7 and taper faced washer 8, and use double nut 2 fastening, in adjustment process, connecting rod 14 moves along axis, pinch roll bearing block 16 one end connects with turning beam 18, the slip of bearing block 16 is become swing by elastic force, swings the axis that the center of circle is turning beam 18, compresses disc spring 13 stroke by rotating adjusting screw(rod) 3, thus change the depressing force of connecting rod 14, and then change top pinch roll pinches power size.Flange 11 is fixed with scale 9, the size of the power of pinching can be conversed according to the displacement regulated.
This invention simplifies former slide plate and pinch roll axis positioning device, meanwhile, the connecting rod 14 of bearing block 16 other end with many group complex form disc springs 13 is connected by bearing pin 15, replaces original cylinder or hydraulic jack, and saves corresponding control device and pipeline.
